Effectiveness of the Suboccipital Inhibition Technique in Forward Head Posture.

Effectiveness of the Suboccipital Inhibition Technique in Individuals With Forward Head Posture: Randomized Controlled Trial

In this randomized controlled experimental trial, it is aimed to verify the effectiveness of applying the suboccipital inhibition technique in altering forward head posture, increasing the craniovertebral angle and decreasing the angle between the chin, the external acoustic meatus and the sternal angle.

Forward head posture (FHP) is defined as misalignment of the head caused by anterior translation of the head in relation to the trunk, The incidence rate of this postural alteration is 66% in individuals between the ages of 20 and 50.

In order to diagnose this alteration, two angles are used: the craniovertebral angle (CVA) and the angle between the chin, the external acoustic meatus and the sternal angle (AMME), with the CVA being the reference angle for diagnosing a FHP. According to the literature, when the CVA is less than 49.9º, there is a FHP.

We decided to use the suboccipital inhibition technique, which according to Eileen DiGiovanna et al (2005), causes a decrease in muscle tension leading to their relaxation. This relaxation, according to Heredia Rizo et al (2012), has significant effects on increasing CVA, which in turn will decrease AMME, resulting in a positive change in FHP.

Inclusion Criteria:

• male and female;
• be over 18 years old;
• have a craniovertebral angle of less than 49.9º.

Exclusion Criteria:

• have a craniovertebral angle greater than 49.9º;
• be a 3rd or 4th year osteopathy student;
• be an osteopath.
